The American Academy of Pediatricians recently released a statement saying that the health benefits of circumcision outweighed the risks. This pronouncement contradicts the Academy’s earlier ruling, just thirteen years ago in 1999, which stated unequivocally that the health benefits of the procedure were slim. The 1999 statement reversed a previous one made in 1989 that said there were good medical reasons for it; but a few years earlier, in 1971, the Academy had officially concluded that it was not a medical necessity. Clearly, circumcision is one of those surgeries about which opinion shifts back and forth over the years.
